Add global timeout to Angular $http

http-backend-decorator.js

  /**
   * @monkeypatch
   * $http gives us no way to add a global timeout default. This is critical
   * for triggering the YOUR_FAULT_TOLERANCE module to handle timeouts after
   * a reasonable amount of time:
   *
   * @upgrade instructions
   * Ensure that arguments[x] is overriding the timeout property of the
   * $httpBackend provider's constructor.
